SPEGZFIQATION forming part of Letters Patent No. 694,869, dated March 4, 1902. Application filed June 26,1901. Serial No. 66,153. (No model.

To all whom it may concern.-

Be it known that I, HENRY WV. LARSSON, a citizen of the United States of Americaand a resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Machines for Longitudinally Dividing Strips of Ratan, of which the followingis a f ull,clear, and exactdescription.

This invention relates to machines for splitting or longitudinally dividing strips of ratan, wood, &c., and has for one of its objects the provision of a' machine whereby a strip which is subsequently triangular or in the form of a segment in cross-section may be slitted or divided longitudinally and in such a manner that the pair of component parts of the strip after it has been slitted, which are complementary to each other, will be tapered endwise and of such a peculiar cross-sectional form as to require in the further operations thereon to bring them to the form of long slender conic segments or whip-sections a much less proportionate trimming or removal of surplus stock at the small frail end portion than at the more bulky and stable butt-end portion. 7

My invention has, furthermore, for its object the provision of means whereby the effective working zone of the cutter or other slitting-tool may be varied relatively to the longitudinal axis of the strip and also whereby the extent of working movement or effective Working zone may be more or less, as desired, for a given line of work.

My invention has, furthermore, for its object the provision of a guide or similar device whereby the strip after it leaves the feeding device may be properly guided during its longitudinal travel, soas to bring the strip into engagement with the knife in proper position laterally of the strip, and alsolthe combination with said guide of means for seating and retaining the strip in the guide.

My invention has, furthermore, for its object the provision of a device whereby the strip after it has passed through the feeding means or is released therefrom may be ejected and fed past the slitting-knife preparatory to the feed of another strip into engagement with the knife.

A further object of my invention may be found in the provision, in combination with other parts of the mechanism, of a member which I preferably term a separating member and which serves for the purpose of separating the component parts of the strip after the latter has been slitted and to keep said component parts away from the sides of the shape cross-sectionallyat all points in its length, of two complementary divisions of the original segmental piece, each of which is ta-c pered from end to end and comprises in all points in its length cross-sectional bulk or area exceeding the cross-sectional area at correspondingpoints of a conic segment, with, how

ever, a greater excess or surplus relatively to any given cross-section of the conic segment at the larger or butthalf or end portion than at the forward half or tip portion, all so that in the final trimming,whereby the strip of the true form of the conic segment or of a form suit-able for acomponent of a whip-stock is produced, there will be required the removal of but a comparatively small amount of the stock at the tip end,which could not withstand without breakage a very considerable trimming, the removal of the greater surplus being done at the butt-end, where the strip has sufficient stability to withstand such proportionately greater removal of stock, and for the production of a machine capable of slitting or dividing the segmental strips into the two parts having shapes such as referred to, the advantages of which have been stated, the invention consists in the combinations and rela V tive or cooperative arrangements of devices or mechanisms, and in the constructions and combinations of parts, all substantially'as' proved machine in a clear and concise man-- ner, I have illustrated in the accompanying chine. 'Fig. 2 is a side viewthereof.

drawings a mechanism which is' adapted for slitting a strip of ratan,'such strip forming a sector-like portion of an originally cylindrical body and being of substantially similar cross-section throughout its length.

In connection with the feeding means whereby a strip is propelled and forcedinto' engagement with a suitable cutter or slitting knife'I deem it essential to provide a device whereby the strip itself may be maintained in its position without any deviation during its longitudinal travel, so that the knife or cutter may perform its work evenly and accurately, the knife being preferably disposed so that the cutting edge thereof will be in parallelism with the out which the knife is supposed to make near the middle portion longitudinally of the strip. 7

While from the foregoing'it will be understood that the position of the strip is in the present instance practically predetermined and unalterable, means are'provided whereby the knife or cutter is'gradually caused to traverse across'the path of the longitudinallymoving strip,so that said cutter may separate the strip into the two component parts, the slitted' sections of which will be of a length corresponding t6 the ratio of longitudinal movement relatively'to the crosswise movement of the knife. i I

In some cases it may be advantageous or desirable to vary the effective working zone ofthe' knife relative to the-longitudinal moveme'nt'of the strip, so that said knife may be caused toengage the strip and slit the same nearer the central body portion-of the strip than'at othertimes, or, vice versa, so that practically my improved machine is adapted forprod ucing whip-stock-forming strips having the tapered portions thereof different, both in degree and in disposition, relatively to the whole length of the strip.

In the accompanying drawings, Figure 1 represents a top view of my improved ma- Fig.3 isan endview looking from the left of Fig. 2 and'on an enlarged scale. Figs. 4 and 5 illustrate a top view and vertical section, respectively, of a part of the feeding mechanism, the guide, and also the cutter or knife. Fig. 6 is a perspective view of the slide whereby the 'cutter,mounted in a holder thereon, is carried and caused to traverse the path of the longitudinally-moving strip. Fig. '7 is a perspective View ofthe knife-holder detached from the slide. Fig; 8 is a diagram illustrating in end view the strip which is to be operated upon by my improved machine and also showing in what manner such strip is ob- 2 est-s69 ing the formation of the 'two complementalparts thereof; and Fig. 11 shows a side view of oneof such co'mplemental parts, the same being exaggerated greatly fromthe appear ance of the strip as produced usually in practice in that while the cross-sectional size is increased the length of-the strip is but a-fraction of that usually made, such exaggeration being, however, to the endv of practicability of illustration and'for the purpose of-the better disclosing the salient feature or form of the strip,'the production of which constitutes a controlling motive in the peculiar organiza-' tion of the present machine:

In the accompanying drawings, in which similar characters denote similar parts, a represents the frame or table of the machine, supporting in journals 1) a-horizontallyedisposed shaft 0, one end of which carries a belt-pulley d, to which power may be imparted from' any ordinary sources Near its other end the shaft 0 carries agear 6 in engagement with an intermediate gearf,journaled on an adjustably-mounted stud g, which.is supported in a slot at the rear of theframe, said gear f being in engagementwitha gear h, secured to the arbor of one of a series of feed-rollers 2', all of which are caused to cooperate-as,

for instance, by pinions j and intermediates 7c. Cooperating withthe rollers 11 are a set of friction-rollers Z, whereby the strip to be operated upon is forced into contact with the feed-rollers '1", said friction-rollers Zbeing in engagement 'withsaid bars, while springs 1' are employed for engaging the'other arms of the angle-levers p, and thus bring the antifriction-rollers Z into contact with the strip, which will thereby be forced into engagement with the feed-rollers 2' above referred to.

Adjusting-screws, such as- 3, may be employed for forming a stop for the downward movement; of the bars m, so as to prevent the rollers Z and i from coming into direct contact with each other after a striphas passed them. i I

The shaft 0 is herein shown as having a worm 25 in engagementwith a suitable wormgear a, secured to-a vertically disposed shaft '22, which may be journaled in the table a, said worm-gear 1b carrying on its upper surface a rollerv w, adapted for engaging a lever 00, which is fulcru'med at y on the table and the free end of 'which is connectedas,-for inceases stance, by a link zwith a, slide 1 which con-Vv stitutes a strip-feeding member forbringing,

a strip into engagement with thefeed-rollers i, above referred to.

In the presentinstance the slide 1 isshown. provided with a dog'2, which may be ,act-u-j ated by-a spring 3 to force said dogintoengagement. with a strip resting upon the ledge 40f the slide, a suitablepositioning-gage (not shown), being provided,'so that the strips may.

be carried'into contact with the feed-rollers in a uniform manner.

Itwill now be understoodthat as. soon as, thefirstset of feed-rollers have engaged the strip the latter will ,be Withdrawn from un-. der 'the dog 2and willbe carried into engage ment successively with theother feed rollers of the series, and thence into contact with a movement in theiframe 0, a spring 15 being employed for normally forcing said plungerguide 5, which is preferably V-shaped incrosssection to correspond tothe tapering crosssection of the. strip; As thestrip enters the guide 5.,it' may come into contact with a.

blade-spring 6,. which constitutes a device whereby the strip is'firmly seated in the guide 5, near one end thereoflwhile near its other end saidstrip is retained in position within the guide 5 .by a resser-bar 7, which in .the,

with theforward end of the presser-bar 7,; while the rear endof said lever Q is connect-. ed .by apin 11 with a. lever 12, resting with.

one end upon a. shoulder l3,.formed in the frame: o,and its other end is engaged by.a plunger 14, which is -mounted for vertical upward, and thus depress the presser-barj', as will be readily understood. 1 4

Inasmuch as it is desirable to withdraw the presser-bar 7 from the guide as soon as the strip has' passed beyond the feed-rollers, means are provided whereby the plunger 14. will :be depressed againstthe action of the spring 15, and consequently the presser-bar 7 will be withdrawn from the guide 5, these means consisting, substantially, of an abutment-screw 16, held in the lastbar m, so that after the strip hasp'assedfromunder the last friction-roller. Z the lever 12 will be depressed by the. descending bar, the spring 7 beingv stronger, as a matter of course, than the spring 15. a

From the foregoingit will be seen that the strip willbepositively guided, the guide 5'being preferably 'stationary,:so that the knife or cutter cooperative with said guide is -or-- ganizedso asto traverse across the longitudinal path 'ofthe strip. This knife or cutter is herein vdesignatedloy 17 and consists, substantially, of a blade haviuganedge 18 and preferably held in a knife-holder. 19, so that said knife may have a slight swingingmove= ment to accommodate itself to the angleof the slit path relative to the longitudinalaxisof the advancing strip, and while in the pres ent instance. Lhave shown said holder :pivoted in alinement withihe. knife-edgeit should be. noted that-said knife-edge maybe disposed in the rear of the pivot-support of the holder, so as to allow the knife to find its own positionby virtue of the force supplied byithe advancing strip On'theotherhand,

it should be noted that the knife-edgeshould holder, and thusnotdefeat theaction oithe proper guiding of theknife-edge transversely of the strip.

holder 19 by screws 20 and check-nuts .21, while at the same time said holder comprises a jaw 22, which may be caused to engage the side of the knife 17-,as, for instance, by a not be remote fronrthe pivot-support of the.

The knife 17 is adjustably heldv within the.

screw 23-'and force the knife against the body'of the holdeiyas clearly shown in Fig. 4. By the adjustment of the screws 20 thekn'ifeedgemaybe adjusted to and from "th eap'ivotal axis of the holder, and by the screw 23 will be readily understood.

The knife-holder 19 is shown pivotally supported on pintles 2a, each having aV-shaped recess to receive the knife-edge and held in or forming a part-of projections 25, formed on; a slide or carrier 26, which is mounted for reciprocation in a frame 27,.secured upon the, I table a.

Also held on the slide 26. is a separating member 28, substantially V-shaped in horizontal section, as is shown by dotted lines inFignri, said member 28 being positioned clamped in its ad ustedposition, the screws 20 serving as a rear bracing for the knife, as.

in the rear-of thefknife 17, substantially with the apex thereof adjacent tothe knife, so that as the strip is fed forward past the knife the complemented branches of the slittedstrip IIO willbe separated and deflected fromthe sides I a l of the knife, inthis manner not only insuriug the knife-against undue wear at the sides thereof, but, furthermore, giving freeaction to the knife when cutting the strip,

Referring to'Figs. 1 and 2, it will be seen thatthe vertical shaft o carries near its .up-

per end a cam 29 in engagement with aroller 30, pivotallyvheld on a slide 31, which may, straddle the shaft o andto which a re'ciprocatory movement isimparted by thecam 29,

The rear end of the slide 31 is provided with a a projectionSZ, adapted to enter arecess .33,

provided therefor in the slide 26 and interposedbetween the cars 34 and 35, projecting from the body portion of theslidefld, asis.

The projection 32 issomewhat narrower than the recess ease. that the slide .26 may be positioned relatively clearly shown in Big. 6.

to the slide 31 tovvary the efiective working zone of the knife 17 relative tothe stationary guide 5, Thisvariation isaccomplished in the present instance by adjusting-screws 36 and 37, the inner ends of which are adapted to enter suitable recesses in the projection 32 and in this manner hold the slide 31 in fixed position relative to the slide 26.

From the foregoing description it will be understood that the knife-operating slide 26 may be adjusted relatively to the slide 31 for an amount equal to the difference insize be tween the projection 32 and the extent of the recess 33. V e I In order to determine the relative positions of the slides 31 and 26, suitable index-marks, such as 38, may be provided on one of said slides and to cooperate with a datum-line provided on the other.

Inasmuch as in some instances it may be desirable to move the knife-supporting slide 26 entirely out of the way in order to obtain access to the guide 5 or some other mechanism, I have herein shown a device whereby the slide 31 may be moved bodily and without being influenced by the action of the cam 29.

,In the construction shown in Fig. -1 it will be seen that the slide 31 carries a lever 39, pivoted on the slide 31, as at 40,'and provided with a pin 41, to which one end of a spring 42 may be secured, while, the other end of said spring may be attached to the base a in any suitable manner.

When the parts arein the position shown in Fig. 1, the spring 42 will of course tend to keep .the roller 30 in contact with the cam 31, while when it is desired to move said slide in the direction of the belt-pulley. d the lever 39 may be swung around its fulcrum 40, in this manner relieving the slide 31 of the action of the spring 42, as will be readily understood.

The operation of my improved machine is as follows: The strip which my machine is particularly adapted to slit forms a segment substantially uniformfrom end to end of a cylindrical body of ratan, from which it is cut somewhat after the manner shown in Fig. 8. The end of the strip may now be passed under the dog 2 of the primary feed-slide 1, which will carry the forward end thereof into con- .tact with the first set of feed-rolls 2', which are continuously rotating, and will therefore pro- -pel the strip so as to be engaged by the entire series of feed-rollers i and friction-rollers Z. As soon as the forward end of the strip has passed beyond the last set of feed-rollersit Will enter the stationary guide 5 and encounter the spring 6, whereby said strip is forced to aseat in said guide, while at the same time the cross-section of the strip at these respective points during the longitudinal travel of the strip, so that by comparison of the first diagram of Fig. 10 with the last one of the series it will be seen that the knife has a travel gradually from left to right, and will therefore slit the strip into two complemental parts, one of which is shown in side View in Fig. '11. This strip may be trimmed to the form of a true slender conic segment or to a modification thereof suitable for a whip-stock-forming strip by the removal of proportionately lessof the surplus relatively to the final crosssectional form to be produced at the tip half of the strip than at the butt portion. As soon as the rear end of the strip has been released from or has passed the last set of feedrollers the last friction-roller Z will immediately be forced toward the roller 1', in this manner raising or withdrawing the presserbar 7 from the guide 5 and leave the strip practically free insaid guide. As the next strip is being fed in and the primary feedslide 1 again makes a forward movement the end of the first strip'may be ejected from the guide 5 by the forward end of a thrust-rod 1 44, the rear of which. is in the present instance pivotally supported on the feed-slide 1, the ejecting end of said rod resting in its inactive position on an inclined guide 45, disposed between the sections of the last feedroller, and the upper face of which will tend to direct the end of the rod 44into alinement with the guide 5 and, striking the rear end of the strip in the guide that has just cleared the last pair of rolls, will thrust the strip through the guide and complete the cutting of the strip, as may be clearly seen in Fig. 5.

The machine may be'so arranged that the knife instead of commencing to diagonally slit the segmental strip at its end may commence such slitting several inches from the end, and thus produce strips which may be finally made into whips having cylindrical butts and forwardly-tapering bodies. Moreover, the rapidity of traverse of the knife across the path of the strip may be easily varied in either of two ways-firstly, by replacing for the cam which operates the knifecutter or slitting tool and the guide through which the strip is fed, and it is not my intention to broadly claim such a mechanism,

such as ratan, on a surface diagonal tot-hestrip, the combination of two members, one member being a guide for the strip having a V- shaped opening whose convergent sides are arranged to constitute substantial bearings for the convergent sides of the tapered strip, and the other member being a dividing-cutter located beyond the guide, one of said members being arranged to be moved relative to the other member and thereby cause the cutter to traverse the area of the V- shaped opening in the guide from one side of'the V to the other, whereby complemental divisions of the, strip are produced. i
